72 | ASIA Miner | September/October 2014 CATERPILLAR has released the new MD5150C Track Drill, the frst of the C Series drills, which feature Cat components - proven reli- able and available from local Cat dealers who also service the drills. According to Caterpillar, the MD5150C delivers top-of-class power and high airfow for fast, effcient drilling of holes from 101.6mm to 152mm in diameter. The MD5150C offers a choice of three different rock drills, patented carousel rod changer, ergonomic cab and many other features that Cat says boost productivity and reduces operating costs. Compared to the MD5125, which the MD5150C replaces, the new drill has 18% more power, a compressor that can deliver 33% more air volume and 40% more air pressure, 19% faster tram speed and 40% greater ground clearance. With less than half as many moving parts as competitive rock drills, it is a simple, reliable design that Cat says offers dependable perfor- mance and exceptional durability. Caterpillar is the only manufacturer offering rock drills designed to be serviced on site to reduce downtime and control costs. Service doesn't require a clean room and there's no need to incur freight costs to ship the rock drill to the OEM for maintenance or to keep a spare rock drill in stock to accommodate maintenance downtime. The rock drill also features an automated lube system which elim- inates the need to stop the machine for manual greasing every two hours. Three different rock drill choices enable matching the selection to the application to achieve the highest production rate. The standard rock drill on the MD5150C is the HPR5128, which uses 51mm drill steel. Also available are the HPR6832 Rock Drill, which can use 68mm speed rod, and the HPR6030 designed for 60mm drill steel. Innovative carousel rod changer Cat says the MD5150C dramatically reduces set-up time, thanks to its innovative carousel rod changer. The rod changer and feed assembly have seven patents pending. The system holds six rods and accommodates two lengths and multiple diameters of drill steel. Powerful dual-rod grippers and a unique gate de- sign let the rod and gate move simultaneously, re- ducing cycle time. The rod changer is supported by a sturdy feed and heavy-duty 2.7 metre boom that extends to 3.3 metres for larger pattern coverage with fewer set- ups. Because the carousel rod changer weighs less and holds more rods than linear models, the boom extension can reach farther and drill deeper while maintaining stability. Holes can be drilled within 610 mm of the highwall, which is 50% closer than with a linear rod changer. High power and big air The MD5150C delivers exceptional power and air- fow for faster, more effcient drilling in hard rock ap- plications, according to Cat. The heart of the power group is the Cat C11 Engine rated at 287kW (385hp) at 1800 rpm. Designed for high performance and ex- cellent fuel effciency, the engine meets US Tier 3 and EU Stage IIIA emis- sions standards. The high-horsepower engine works as a system with a high-capacity air compressor to optimize air fow. An oversized, high-eff- ciency cooling system further improves performance and life. Cab enhances safety The cab on the MD5150C is designed to enhance safety and productivity. It is ROPS/FOPS-certifed and provides numerous shutdown controls ac- cessible from the ground. Large windows, streamlined front structures and a skylight enhance visibility, as do well-placed mirrors and a high-resolution camera. The front window provides an emergency exit. To boost operator comfort and productivity, the cab features automat- ic climate control, excellent ventilation, a fully adjustable seat, ergonom- ic controls and switches, and low sound levels (about 80 decibels). To further improve operator productivity, the machine is equipped with a smart drill monitoring system that tracks changes in rock formation and automatically adjusts impact and feed pressure based on hard- ness of the rock. Anti-jam, anti-plunge and anti-plug capabilities keep the track drill working effciently and extend drill string life. Quick maintenance Service technicians beneft from the simple component layout and con- venient service access. A walk-in service station provides easy access to major service points for the engine, compressor, air conditioner, hy- draulic valves and more. A boom-mounted camera provides a view of the front of the drill while working inside the service center. In addition to its serviceable design, the new track drill leverages ex- clusive Caterpillar technologies that maximize uptime. Cat Electronic Technician speeds the troubleshooting process, improving repair ac- curacy and reducing downtime. Cat Product Link allows remote mon- itoring of machine location, service meter hours, fuel usage and other critical factors, providing managers the information they need to opti- mize utilization and reduce costs. There are three different rock drill choices with the MD5150C Track Drill which enable matching the selec- tion to the application to achieve the highest production rate. New Cat MD5150C Track Drill
